Sigur Rós: Heima the UK premiere at the Cecil Sharp House on the 24th October 2007

Last summer, at the end of an extensive world tour, Sigur Rós returned to Iceland and played a series of free, unannounced concerts around their homeland. These concerts took place in unexpected venues - from an abandoned fish factory, to a protest camp at the edge of a controversial dam, to a far-flung community hall, with tea and cakes for refreshment.

The entire tour was filmed and the result is Heima, a cinematic and musical feast. Sigur Rós' big, beautiful sound resonates against Iceland's majestic landscapes. This, along with intimate interviews with the band, offers a captivating insight into their music, their inspirations and their sense of home.

This gig is part of the BBC's Electric Proms festival which takes place across Camden on 24-28 October. Over 80 artists are performing and they've all been encouraged to create something unique for their shows. The gigs will be broadcast across BBC TV, radio and will be online to watch at bbc.co.uk/electricproms
